SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 328,347, dated October 13, 1885.

Application filed July 11, 1885. Serial No. 171,345.

To all whom t may concern:

Beit known that I, NEWTON J. SKAGGs, a citizen of the `United States, residing at Montgomery, in the county of Montgomery and State of Alabama, have invented certain new and useful Improvements in Sash-Balances; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or iignres of reference marked thereon, which forni a part of this specification.

lFigure 1 of the drawings is a representation of front elevation with parts broken away. Fig. 2 is a horizontal section. Fig. 3 is avertical section.

This invention relates to sash-balances and sash-locks; and it consists in the construction and novel combination oi' parts, as will be herenfter fully described, and particularly pointed out in the claim.

Referring by letter to the accompanying drawings, A designates the window-frame, which is constructed in the ordinary manner, with side and top strips, which form the guides in which the upper and lower sashes work when operated.

B and C designate the upper and lower sashes, which work in the guides when the sashes are moved.

The window-frame is provided in one of its sides with a set of lnortises or notches, D, located at suitable or desired intervals to fix the height to which the sash is to be adjusted. On the inner faces ofthe sash-Stiles llgrooves G are made, in which the sash-bolts I-I work. These sash-bolts H are provided with horizontal slots I, through which pins or studs J extend, said pins or studs being seated in the side sash-Stiles near the side of the windowfra-nie, which is provided with the bolt-seats.

At the top of thc windowlralning, on the under face of the top cross-piece, are provided bearing-lugs K for a shaft, L, on which a grooved pulley, M, works.

The upper sash-rail oi' the lower sash is provided on its inner face with a catch-plate or keeper, N.

(No model.)

-To the top rail ofthe upper sash a cord, 4 is secured, and this cord runs over the pnlh M and down below the top rail of the low` sash, and is knotted at proper places, tl knots Q being designed to engage the keepe plate N, to hold the sashes balanced at the d sired points to which they may be adjuste` either to close them or to afl-'ord ventilation.

The keeper -plate N has a shoulder, h which rests against the face of the top rail the lower sash, being secured in place l screws, and is provided with a downwardl,l projecting lip, R, against which the desirr knot in the cord O rests or inipinges to ho` the sashes in the positions to which they ma have been adjusted. The top rail of the low sash is provided with a vertical groove for tl cord.

I ain aware that it is not new to provide tl upper sash of a window with a pulley, a rol passing over said pulley and secured at oi end to the top rail of the upper sash, the o] posite end of the cord being in loop form, f as to engage knobs on the lower sash, an thereby hold the respective sashes in desire positions. I ain also aware that it is not ne to recess the easing at intervals and previ the sashes with bolts to engage the said n cesses, and therefore do not claim such device: broadly but,

Having thus fully described my inventioi what I claim as new, and desire to secure b Letters Patent ofthe United States, is-

The combination, with the casing havin the upper horizontal pulley, M, and the up per .and lower sashes, of the cord O, havin a plurality of knots and secured at its uppe end to the upper sash, the plate N, having th shoulder N secured to the top rail ofthe lowe sash and arranged to receive the said cori" all arranged for joint operation, substantiall as shown and described.

In testimony whereof I affix my signature i presence ol' two witnesses.

NEVTON J. SKAGGS.
